Example tokens include operators such as + and *, variable names such as myVar, or strings such as "my string".Įach token is associated with a scope that defines the context of the token. Tokens are one or more characters that are part of the same program element. TextMate grammars are a structured collection of Oniguruma regular expressions and are typically written as a plist or JSON. VS Code uses TextMate grammars to break text into a list of tokens.
